CLAMPING DEVICE.

Specification of Letters Patent.

Patented June 5, 1917.

Application filed January 4, 1917. Serial No. 140,620.

To all whom it may concern:

Be it known that I, GEORGE C. KINs- FATHER, a citizen of the United. States, residing at Livingston, in the county of Park and State'of Montana, have invented certain new and useful Improvements in Clamping Devices, of which the following is a specification.

The present invention relates to improvements in clamping devices particularly designed for adjustably connecting a tool element to a supporting frame member of an implement.

The main object in view is to provide a device of this character most readily facilitating the operation of shifting the position of the tool upon its support or adjusting said element itself when in some particular position. according tothe requirements in use. This is advantageously accomplished by a mere loosening of the parts without a removal thereof, so thatthe likelihood of misplacement of the requisite members is remote.

For a full understanding of the present invention, reference is to be had to the fol lowing description and the accompanying drawings, in which:

Figure 1 is a side elevation of my clamping membershowing its application to a supporting element of an implement, said supporting element being shown in section.

Fig. 2 is a bottom plan view parts being shown in section.

Fig. 3 is a top shown in section.

Fig. 4 is a vertical sectional view on the plan view, parts being line 4-4; of Fig. 2.

Fig. 5 is a perspective view of the clip member.

Fig. 6 is a perspective view of the wedge elementl Fig. 7 is a sectional view showing the adaptation of the device to a rectangular supporting member.

Figs. 8 and 9 are fragmentary plan views showing more particularly the formation of the wedge member for different types of tool elements.

Throughout the following detail descrip' tion, and on the several figures of the drawings, similar parts are referred to by like reference characters.

Referring to the drawings A represents a supporting beam or element of the frame of an implement, for instance, a harrow or a cultivator, and B the shank of a tool element adapted to be supportedby said member and adjustable with relation thereto. The subject matter of this invention is a clamping device for connecting the tool element B to the supporting member A and consists of a clip 1 of U-shape form, embracing the supporting beam A and receiving the shank of the tool element B, the sides of the clip being slotted as indicated at 2 for this purpose. The sides of the clip are connected at their end portions by a bolt or similar adjustable connecting means 3 extending through alincd apertures 4 and as apparent the side members may be drawn closer together by screwing up the nut 5 of the bolt.

A particular feature of the device is the wedge member 6 which is received in the slots 2 of the clip at one side of the shank of the tool element B, and opposite the supporting member A. This wedge memher is wider at its central portion and provided with inclined cam surfaces 7 each of which coacts with an end wall of one of the slots 2, said end wall of each slot being 001'- respondingly inclined so as to permit said wall to ride on its cooperating cam surface. The wedge member is preferably formed with a headed extremity 8 and the other end portion is formed with an aperture 9 to receive a cotter pin or like fastening member 9 so as to insure against loss of said member.

It will be understood that the clip 1 is of yieldable material so that when the clamping member 3 is adjusted so as to draw the sides of the clip toward each other, the wedge member 6 by reason of the cooperation of the cam surfaces 7 with the end walls of the slots will press the shank of the tool element B against the supporting member A. When the clamping means 3 is loosened, however, the sides of the clip will spread and release the clamping action thereby permitting the clip to be shifted longitudinally of the supporting member A or rotatively thereabout, or the loosening of the said clip permits the shank of the tool member B to be adjusted vertically as may be desired. A

threefold adjustment is thus obtained by a iimple adjustment of the clamping mem- Where the supporting beam A of the implement is round I preferably provide a set screw at the closed end of the clip which is adapted for impingement against the supporting member A. so as. to hold the tool element locked at its adjusted position.

In Fig. 7 I have shown the adaptation of the clamping device for supporting beams of rectangular cross sectional form. The cooperation of the parts is identical to that described above excepting that with this form the set screw 10 may be dispensed with.

In Fig. 8 it will be observed that the shank of the tool member C is round in form and I preferably form the edge of the wedge member 6 which coacts with the shank concave so that said wedge member will be provided with a seat to receive the tool member shank.

In Fig. 9 the shank of the tool member D is rectangular and under such condition it is preferable to form the edge of the wedge member 6 with a V-shape groove so as to fit the corner of the shank.

As this clamping device may easily be modified to suit various forms of supporting members and tool elements I do not \clesire to be limited to those forms which are disclosed in the official drawing.

Having thus described my invention, what I claim as new is:

1. The combination with an implement frame supporting member, of a. clamping device comprising a clip. embracing the supporting member and adaptedto receive a tool element to bear against the supporting member, clamping means for drawing the sides of the clip together, and means operable incident to movement of the sides to clamp the tool element against the supporting member.

2. The combination with an implement frame supporting member, of a clamping device comprising a clip embracing. the supporting member and adapted to receive a tool element to bear against the supporting member at one side, a clamping member cooperating with the clip, and movable means arranged at the other side of said tool element operable by the clamping member to press said tool element against the supporting member.

3. The combination with an implement frame supporting member, of a clamping device comprising a clip embracing the supporting member and slotted to receive. a tool element to bear against said supporting member, connecting means for the sides of said clip, and means arranged in the slot with the tool element for imparting clamping action to the latter upon actuation of the sides aforesaid by the connecting means.

4. The combination with an implement frame supporting member, of a clamping device comprising a clip connected to the supporting member and adapted to receive a tool element to bear against the same, adjustable means connecting the sides of the clip operable to compress the clip, and means intermediate the tool element and the sides of the clip for imparting clamping action to the tool element upon adjustment of said adjustable means.

5. The combination with an implement frame supporting member, of a clamping device comprising a clip embracing the supporting member and slotted to receive a tool element to bear against said supporting member, a removable member in said slot with the tool element so formed as to impart clamping action to said tool element, and means connecting the sides of the clip for drawing the sides, together to produce the clamping action of the removable member as aforesaid.

6. The combination with an implement frame supporting member, of a clamping device comprising a clip embracing the supporting member and slotted to receive atool element to bear against said supporting member, a removable member seated in the slot with the tool element having a cam surface cobperating with the side of the clip, and means for compressing the clip to cause said sides to ride on the cam surface aforesaid and thereby clamp the tool element.

. 7 The combination with an implement frame supporting member, of a clamping device comprising a clip embracing the supporting member and adapted to receive a tool element to bear against said supporting member, a wedge member seated against the tool elementand havingoppositely arranged cam surfaces cooperating with the sides of said clip, and means for compressmg the sldes to cause the same to r1de on the cam surfaces and impart clamping action to the tool element through said wedge member.

8. The combination with an implement frame supporting member, of a clamping device comprising a yieldable clip of U- shape form, the sides of said clip being provided with diametrically opposite slots to receive a tool element to bear against said supporting member, a wedge element arranged transversely 'ofthe clip in the slots aforesaid and against the tool element, and adjustable means connecting the ends of the sides for actuating the wedge member upon compression of said sides.

9. The combination with an implement frame supporting member, of a clamping device comprising a yieldable clip of U- sides for actuating the Wedge member upon shape form, the sides of said clip being procompression of said sides, and auxiliary '10 vided with diametrically opposite slots to means carried by said clip cooperative with receive a tool element to bear against said the supporting member to hold the clampsupporting member, a wedge element aring device at adjusted positions.
